Question a
The given cube has length,


l = 5cm

If the cube us enlarged by a scale factor of 2, then the enlarged cube has length,


L=2 * 5cm = 10cm

Question b.

The volume of the original cube is



v = {5}^(3) = 125 {cm}^(3)

To find the volume of the enlarged cube, multiply the volume of the original cube by 2³.


The volume of the enlarged cube is


V = {2}^(3) * 125 = 1000 {cm}^(3)


Question C


The surface area of the original cube is

s.a = 6 {l}^(2)


s.a = 6 * {5}^(2) = 150 {cm}^(2)


To find the surface area of the enlarged cube multiply the surface area of the original cube by 2².



S. A = {2}^(2) * 150 = 600 {cm}^(2)
